Works great, easy to use, dependable way to get safe water.

5 Matthew M
A bottle full of Mt Baker lake and a little uv light makes me not get sick, 10/10 would recommend

5 Will S
Pros:- light weight- easy to use- batteries can be found anywhere- no taste like other methods of sterilization( iodine/ chlorine) Cons:- need to carry spare batteries- takes 90 seconds of stirring I have had this product for a couple years now and it still works great. I 've never gotten sick from drinking the water from it. It is really great for backpacking and travel in less developed country. If you use the lithium AA's it really takes forever to run out. However it's always a good idea to have spare batteries.

5 Curran O
Great purifier, light, easy to find AA batteries. Lighter but also larger than my other similar device. Weight is good for the trail

I have had this for over six months, used on several camping and hunting trips, great options, especially when there is running water everywhere you are going

[ I ordered this 5 days before my elk hunt, I received it two days after ordering. Got water right from a mountain creek. The water flowed great through the filter with no issues, it was very easy to use and the water tasted delicious! This will always be in my pack.

5 Mountainmankeary
Simply indispensable for backcountry adventures. I consider it the best option in the entire market. Proved itself beyond worthy on a high mountain deer hunt. I 'll never go within it again

5 Randy L
Super easy, fast, portable. Used it multiple times a day over multiple days on a Colorado elk hunt.

5 Martin B
Purchased for long runs 20+ miles out in the national parks and trails. Even with hydration vest and water bladder, replenishing water is still something I keep thinking when the time goes on. Love this bottle filter, being a good size of 1L to fill my bottles and bladder. Quickly filters well, easy to squeeze and use. Most of all is fairly small to pack away into my vest and continue my runs with no issue. Recommend to anyone who want a nice easy, packable, bottle filterer.

5 Bethany I
I am impressed by the weight of the bottle; I trail run so it was easy to carry. The water tasted fresh and was easy to drink. I would recommend to anyone who enjoys long outdoor activities!

5 Trenton B
[ This bottle is excellent. Fill the bottle, put a filter puck in the screw on cap, and drink; it does not get any simpler. I went on a few multiday trips with this bottle in stow, and I have yet to find a bottle more packable. A few inches is all you need as far as space goes. Basically, it take about as much space as a tennis ball and it's very lightweight. I was worried that it might be a little tough to clean, but that's not the case. I have narrow bottle brushes to scrub if need be, but honestly fill it with soap and water when you get home, shake it out, and hang it upside down.

5 Trevor F
[ I ’ ve used it to filter well water in the desert, trail runs in the mountains, and fly fishing in the creek. It ’s compact enough for easy storage but has enough volume so that you could use it as your only bottle. The flow is decent and the cap is secure even knocking around rocks. This little thing just works. I haven ’ t had to clean it yet but the directions seem very simple. Highly recommend for any trip where you need to filter water!

5 Kristen C
[ This was a great addition to my field work pack for a recent river survey. It is lightweight water bottle option, with the added bonus of the water filter to make sure the water was clean prior to drinking.

5 Brian F
[ I have tried just about every ultralight water filtration system on the market and been repeatedly impressed by the BeFree's flow rate. The BeFree AC seems even faster than the original model, filling up my one- liter water bottle within seconds. After receiving this system in the mail, I tested it on multiple dayhikes and trail runs. It held up well, and the collapsible bottle made it exceedingly easy to pack. I usually stuffed it into the mesh front pocket of my backpack so I would have easy access to it when I came across a stream. I filtered probably a few dozen liters and saw no decline in the flow rate. The bottle's large mouth opening makes filling up a breeze. Throw on the filter cartridge and cap and you can drink straight from the bottle or filter water into another container. Simply put, this filtration system is very quick and easy to use. Because I saw no decline in flow rate, I had no reason to clean the filter cartridge in the field, but I know that this is also easy. All you have to do is fill the bottle with clean water, put on the filter cartridge and cap, and shake. I know from using the original BeFree that this method works to restore the flow when gunk from water sources clogs up the filter on long backpacking trips. This method is much easier than filters that require backflushing. The BeFree AC is also slightly sleeker than the original version, which makes it easier to keep the filter in your pocket during the winter so it does n't freeze. I have several long backpacking trips and mountain climbs scheduled this year, and I will be taking the BeFree AC as my primary water filtration system. Katadyn Group gave me this free product to try.

5 Fiorella F
[ I have always been skeptical of soft or flexy bottles because they don ’ t seem very durable, but this bottle exceeded my expectations! I accidentally stepped on it and it was totally fine. The flexible bottle made it super packable, as it is about the size of my fist when empty. There is also a loop when you can attach a carabiner to it, which is nice because it makes it easily accessible being that the soft bottle might be hard to get into a side pocket on a pack when the pack is full. It was also very easy to use because there aren ’ t many components. One you put it together you just have to run a liter of water through it to prep the bottle, and then you ’ re good to go. When filtering out the first liter it looks like the flow rate is super slow, but it ’s perfect when you ’ re actually drinking from the bottle. I used this bottle while hiking and camping at Table Rock State Park. The creek water had some silt in it as the area had just experienced some wildfires, but the water filtered through clear and tasted great. Finally cleaning the little was super simple too. You either shake the bottle or swish the filter in clean water, and you ’ re set. A deep clean consists of running a bleach/water solution through the filter. Overall I am super happy with this product and will definitely be taking it on all of my hiking/backpacking trips! Katadyn Group gave me this free product to try.

I have a collection of water filters including the older model MSR hyperflow filter and the new 3 ounce Sawyer, but this one ca n't help but make you smile when used. The Sawyer is a pain to fill the dirty water bag, used a Platypus bag with only slightly better results. The older Hyperflow filter is a pain to backflush and gets hard to pump, replaced the filter but the new one is even harder to pump. This new high- dollar filter leaked water out the handle- side of the pump when new, took it apart and spread the lube around better and it sealed up fine. Used it on a overnight pack and was very very happy with how little effort the pump takes and how fast it fills a bottle. It is a little bigger than the hyperflow but sooo much better. The inlet filter looks overkill and will be hard to use in a small water seep but I am sure it will work out. Overall it is so fast and easy to use it is well worth the price.

Purifying some ice cold water in the Weminuche Wilderness! Performs flawlessly! Reminds me of camping as a child pumping water from the pump in the ground! So easy to use it's a breeze. I recommend this product A++

5 JohnnyTN
I could say it's the most advanced, easy to use portable purifier on the market, but that's old news. Yes, it is bulky and heavy for backpacking compared to filtering- only options, but it purifies(!), and freezing will not render it unusable. It is also perfect for international travel, mission trips, and home emergency kits.

5 Dean
[ I bought this for my daughter who is now in Nicaragua. With widespread contamination of wild water( lakes, rivers etc) with human feces and even tap water uncertain, I wanted the anti virus feature. I have used Sweetwater, and other brands for bacteria and cysts but the no chemical virus elimination is promising. Since I have not tested this in a clinical lab setting I ca n't promise you there are no viruses. I will say the thing pumps water like no tomorrow and the design seems sturdy and simple. While most people are using bottled water and even Coke when the local retail does n't do bottled water, my daughter is free as bird to pump her own. I will say that I have some other brand bottles besides Nalgene and they do n't work with the clean side threads on the Guardian. So you must carry at least one Nalgene standard widemouth with you.

5 TYHAC
[ Used for a weeklong backpacking trip, end to end on IR. Worked flawlessly in standing inland lakes, flowing and shallow trickling streams. Auto backwash is excellent. Packs well. Not sure how it can be improved!

[ The Katadyn filter is so easy to care for and has no odd tastes or after effects. We love it

5 Joseph F
[ I recently had the opportunity to test the BeFree AC 0. 5L Microfilter Bottle on several hikes in the Rocky Mountains, ranging from quick trail runs to full- day excursions in remote areas. The BeFree system is intuitive. I was able to fill the bottle from streams and lakes without any hassle. The wide mouth makes scooping water fast, and the filter screws on easily. I didn ’ t need to read any instructions to get going — just fill, squeeze, and drink. It ’s perfect for anyone who wants a grab- and- go filtration system. The bottle itself feels a little lighter and thinner than traditional hard- sided bottles, but it held up well during my trips. I dropped it a couple of times on rocky ground, and it didn ’ t puncture or split. The filter remained intact and operational. While I wouldn ’ t want to step on it or pack it at the bottom of a loaded bag, for typical hiking use it ’s more than durable enough. The flow rate is impressive for a filter of this size. Unlike some filters where you have to work hard to get a drink, the BeFree allows a smooth, fast flow with just a gentle squeeze. I never felt like I had to wait to quench my thirst — even after several days of use. Cleaning was super simple. I just shook the bottle with clean water or swirled it a few times to dislodge any debris. For longer trips, I ’ d still want to do a deeper clean periodically, but for short- term use it couldn ’ t be easier. What I Liked: Lightweight and ultra- packable Great flow rate No backflushing tools or complex cleaning steps Convenient size for day hikes or trail runs Room for Improvement: A slightly more rugged bottle material would boost confidence when using in rough terrain An easier to open cap would be appreciated. My hope is it gets easier with time. Who I ’ d Recommend This To: Trail runners and fast- packers Day hikers Ultralight backpackers Anyone who wants a simple, compact backup water filter for emergency kits or travel

5 Monica E
[ Took this little guy to the desert for my mountain biking trip. Stopped at a reservoir for a dip& to hydrate, and this bottle is PERFECT. It folds up small and the carbon filter makes the water taste well, tasteless. Can ’ t wait to take this out while I ’ m working in the backcountry and need a quick water break. It ’ ll be perfect for bikepacking this summer too. It filters pretty quickly if you suck on it like a sports bottle, but it still filters quickly if you ’ re dripping/squeezing it. I ’ m interested in snagging the 1L bottle for hot days on the trail. It ’s way quicker and easier than using a pump filter or waiting on a big gravity filter, but it pairs perfectly with those. Disclosure- Katadyn Group gave me this free product to try.

5 Mohammad E
[ Because it ’s performance very well, it ’s easily portable, and I had no issues with it.

5 Jayson W
[ Katadyn Group gave me this free product to try. Out in the wild filtering rain water tonight. It ’s. 5l so not the biggest size but fits great in my day pack and weighs next to nothing. If you are in need of a small filter and rez package this is the ticket. Makes the water nice and clean. No gi upset so far so I ’ d say it ’s working. I ’ ve dropped it on rocks and sticks and no punctures had it in my pack full of water and it never burst so pretty tough little bladder. The water taste pretty fresh with minimal aftertaste I ’ ve been using it in streams and with rain water so far and give it two thumbs up. The flow is what you would expect slow but gets the job done. All in all the perfect little space saving bladder with filter. Folds up nice and small. Get one and store it in your pack or car or boat or what ever you won ’ t regret it when you need it.

5 Mountaintop Joe
Great filter. I still have the one which was purchased with my Miniworks, but I decided I wanted to have a spare on hand in case that one broke or became too worn to be used. No complaints on them.

5 Kav47
I have had a WaterWorks filter for years. The only time I had to replace the filter was because I dropped it on cement while cleaning it. I do try to filter the cleanest water I can find and, when it is cloudy( full of St. Helen's ash for instance) I collect it in a bucket and let it settle before filtering if possible.

5 Gone C.
I 've never had a slight question about these filters effectiveness. I depend on them to keep me safe on the trail and happy when I return home.

1. Thank You for continuing to offer the ceramic filter for the water purifier. 2. I have used your water filter and your little backpacking stove for many, many ears. Outstanding equipment!

5 Acu P.
I have a circa 1992 Waterworks filter that I used long ago and put back into storage. After contacting MSR to see if I could use this cartridge in my old filter,( they responded with an email confirmation), I purchased this. Took it on a recent 5- day trip to Norther Wisconsin. Initially in a tannin- filled lake, it pumped quickly. Then it plugged up after 1. 5 liters( hard pumping, trickle). I took out the cleaning pad, cleaned and got it working again at full- rate. It regularly plugged but I was warned that this would occur in this type of water. As we paddled to other lakes, I found that the performance improved( could pump 4+ liters of water with no cleaning necessary). There was one other filter in the group and people were impressed with this filter's performance and field maintainability. The filter then would not draw water in on the suction stroke. I took it apart, and found that there was grit in the umbrella valve. Cleaned it and put the pump back together and it worked flawlessly again. I 'm highly impressed with the overall performance. I like the internal carbon matrix that can also filter out bad taste.
